If a person claims to know anything could it be disproven by saying 'prove that we are not in a simulation'?

The issue here, as it often is, is that colloquial English is horribly ambiguous, which makes any sort of precise and rigorous discussion difficult. But with sufficient effort, it is possible to make ...

Are we living in a simulation? The evidence

I would like to argue that the topic (especially the search for proof for it) is rather useless. With a search for evidence, this topic is very similar to the topic of the search for evidence that God ...

If we live in a simulated world, doesn't there have to be a first world that's real?

We can not carry the argument past the first step because if our physical laws are simulated then we know nothing about the "physics" of the world that does the simulating. In particular, it may make ...

Are we living in a simulation? The evidence

I propose that we cannot know whether we are living in a simulation. One of the ways to detect a simulation supposedly is to detect errors from the inside. But there is no reason whatsoever to ...

Are we living in a simulation? The evidence

To focus on the title of the question, there is rather little active research being done around this question, but I'll share what I know. First is a paper from 2012, Constraints on the Universe as a ...

Did David Deutsch really disprove the Simulation Hypothesis?

To be honest, I couldn't exactly follow your construction. But I can say that Deutsch is definitely not using an impossible scenario. He is actually adapting the Cantor Diagonalisation Argument which ...

Are we living in a simulation? The evidence

Of course it is possible that you are "living" in a simulation right now! I'd say it is about 50% chance. we call it dreaming and it happens every night. Well, you might say, that is pure ...

Are we living in a simulation? The evidence

It is impossible for us to find evidence that we are living in a simulation. All computers that can perform more than a very minimal set of operations are universal computers. A universal computer can ...

If a person claims to know anything could it be disproven by saying 'prove that we are not in a simulation'?

Consider what the second person said: You cannot prove that we are not in a simulation and that anything is real, hence you cannot prove that your claim was true. This may be an example of an ...

Can it be shown that video games have in some way impacted philosophy or vice versa?

What I'm asking is what is the impact of video games on philosophy. Can I read somewhere about it? I am simply posting some materials which may be useful. Playing with Good and Evil: Video games and ...

Did David Deutsch really disprove the Simulation Hypothesis?

Deutsch is restating some well known results in the theory of computation discovered by Godel and Turing. The result explains that not all functions can be calculated by a computer. This is not a ...

Are we living in a simulation? The evidence

We know a lot about simulations, and how they work. Lets look for some of those artifacts in the real world. Simulations use code, which includes various types of numbers - integers, floats etc. ...

How does the 'Brain in a Vat Argument' differ from the 'Simulation Argument'?

One difference between the brain in a vat argument and the simulation argument is their motivations. The brain in a vat argument is motivated to support skepticism through doubting one's senses. The ...

Are we living in a simulation? The evidence

Suppose that what we call this reality is a simulation. Then by analogy, it is plausible that within this reality we can build machines that contain simulations. Also by analogy one can infer that it ...

How does the 'Brain in a Vat Argument' differ from the 'Simulation Argument'?

There is indeed a fundamental difference. The Brain-in-a-vat seems within the reach of even human technology. In other words, it is a highly convincing and realistic scenario. A brain in a vat would ...

If a person claims to know anything could it be disproven by saying 'prove that we are not in a simulation'?

No, that argument is not logically correct because knowledge need not be absolute, but can be relative. To know the sky is blue means to connect the perception of the atmosphere that we call the sky ...

Consciousness in Simulation theory & AI, why do some believe that it is even possible?

What is consciousness? There isn't a commonly accepted definition of consciousness (that I'm aware of). This lack of a precise definition presents the first and biggest problem in providing a concrete ...

Is it possible to simulate a reality like ours using other logic than classical logic?

Just to expand a little on Conifold's comments. Logic is not reality, it is something we use to help us describe reality and form representations of it. Logic helps us to organise information and ...

If we live in a simulated world, doesn't there have to be a first world that's real?

Also... as far as the Simulation Argument, you have to ask "what difference would it make?". If we're simulated, what would be different from if we're real? How would it affect things? If it would ...
